[SENSe:]ADEMod:PM:AFSPectrum:RESult? <result type>
This command reads out measurement results of the AF spectrum of the PM demodulated signal with the
specified result type. The data format of the output data is determined with the FORMat command.
Note: Traces in the VIEW state cannot be queried.
Parameter: <result type>: WRITe The current measurement results are returned.
AVERage The measurement results averaged over the given
number of measurements are returned.
MAXHold The maximum result determined over the given
number of measurements is returned.
MINHold The minimum result determined over the given
number of measurements is returned.
Note:
The specified result type must be one of those configured with the command
[SENSe:]ADEMod:PM:AFSPectrum[:TYPE]. Otherwise a query error will be generated.
Returned values:
ASCII format (FORMat ASCII):
In this case, the command returns a comma-separated list (comma separated values = CSV)
of the measured values in floating-point format. The output unit is dBm with logarithmic display
and volt with linear display.
Binary format (FORMat REAL,32):
In this case the command returns binary data (definite length block data to IEEE 488.2), each
measured value being formatted in 32-bit IEEE 754 floating point format. When seen
schematically, the return string is structured as follows:
#41024<value1><value2>...<value n>
with
#4 number of digits (4 in the example) of the following number of data
bytes
1024 number of following data bytes (# of DataBytes, 1024 in the example)
<value x> 4 byte floating point value
